BMS With I2C, SMBus Communication protocol for Li-ion/Li-Polymer/LiFePO4 5S-10S Battery Pack
Features and Benefits
Programmable BMS with SMBus, I2C Communication protocol
1.Battery Management circuit board with SMBus for 5S~15S 80A Li-ion/Li-polymer and LiFePO4 battery pack;
2.BMS/PCB/PCM applies for 8S/9S/10S/11S/12S/13S/14S/15S/16S cells Li-ion/Li-polymer and LiFePO4 battery pack;
3.To prevent the battery packs from overcharge,overdischarge,over current, over temperature ,short circuit ;
4.The Maximal working current: 80A;
5.Compatible with both Li-ion/Li-polymer and LiFePO4 cells.
HCX-D298v1 BMS mainly designed based on TI chips, TIBQ78350+BQ76940/BQ76930/BQ76940, and the mosfets for discharge and charge current we mainly use IRF4310/IRF3207/IRF1404 (Only for reference), the specified parameters as below (all the logical parameters are adjustable from software).
(Note: the pictures or parameters in this data sheet are only for your reference, those possibly could be different from the ones you will order. Due to the upgrading of the Hardware/Firmware/Software, Characteristics subject to change without notice, for more information, please contact our technical engineers by email: info@bestechpower.com
